宁夏作物学会国营农场组于4月27至30日组织了春小麦苗期生长考察,参加考察人员有来自农垦、劳改、科研、教学、生产系统的科技干部、学会会员共51人。考察了代表宁夏淡灰钙土、老户地及灌淤土三种土壤类型,产量水平分别为五、六、八百斤的黄羊滩农场、渠口农场及连湖农场。这些国营农场近年来生产发展很快,它们总结了一套深翻改土、平整土地;秸秆还田、种植绿肥;经济用肥、改革施肥体系;深施肥、浅播种;以及化学除草、双行靠等措施,对从事科研、教学及县社工作的同志启发很大。这次考察紧密联系生产实际,组成了土壤水分、根系发育、出苗率三个测试组,白天深入到不同类型
The State Farm Team of Ningxia Crop Institute organized the investigation of spring wheat seedling growth from April 27 to April 30, with a total of 51 scientific and technological cadres and members from the field of farming, labor reform, scientific research, teaching and production system. The survey was conducted on Huangyangtan Farm, Quankou Farm and Lianhu Farm representing three soil types of Ningxia light gray soil, old land and irrigation silt, with output levels of five, six and eighty catties respectively. In recent years, these state-owned farms have witnessed rapid development of production. They summed up a set of deep-turning land for improvement and land leveling; returning straw to green land to green manure; economic use of fertilizer and reforming fertilization systems; deep fertilization and shallow sowing; and chemical weeding, By means of such measures, they are greatly inspired by the comrades engaged in scientific research, teaching and county work. The study closely linked to the actual production, formed the soil moisture, root development, emergence rate of three test groups, daytime depth to different types
